ABSTRACT

Brain damage in acute sepsis may be associated with poor long-term outcomes that impair reintegration into society. We aimed to clarify whether brain volume reduction occurs during the acute phase of sepsis in patients with acute brain damage. In this prospective, noninterventional observational study, brain volume reduction was evaluated by comparing head computed tomography findings at admission with those obtained during hospitalization. We examined the association between brain volume reduction and performance of the activities of daily living in 85 consecutive patients (mean age, 77 ± 12.7 years) with sepsis or septic shock. The bicaudate ratio increased in 38/58 (65.5%) patients, Evans index increased in 35/58 (60.3%) patients, and brain volume by volumetry decreased in 46/58 (79.3%) patients from the first to the second measurement, with significant increases in the bicaudate ratio (P < 0.0001) and Evans index (P = 0.0005) and a significant decrease in the brain volume by volumetry (P < 0.0001). The change rate for brain volume by volumetry was significantly correlated with the Katz index (ρ = -0.3790, P = 0.0094). In the acute phase of sepsis in this sample of older patients, 60-79% of patients showed decreased brain volumes. This was associated with a decreased capacity for performing activities of daily living.

ABSTRACT

Purpose: The characteristics of patients with severe COVID-19 pneumonia who underwent direct hemoperfusion using polymyxin B-immobilized fiber column (PMX-DHP), in addition to steroids and immunomodulators, remain unclear. Patients and Methods: We conducted a retrospective observational study on 31 patients with severe COVID-19 pneumonia treated with PMX-DHP in an intensive care unit (ICU) from December 2020 to September 2021. Results: Outcomes 28 days after admission to the ICU were 20 in the survival group and 11 in the death group. Parameters significantly different between the survival and death group before PMX-DHP were percentage of invasive mechanical ventilation (25% vs 72.7%, P = 0.0209), PaO2/FIO2 (P/F) ratio (104.5 vs 75, P = 0.0317), and sequential organ failure assessment (SOFA) score (2 vs 3, P = 0.0356). Invasive mechanical ventilation avoidance rate was significantly different between the survival (100%) and death group (0%) (P = 0.0012). P/F ratio, respiratory ratio (RR), and lymphocyte counts improved significantly after PMX-DHP for all patients. The lymphocyte counts changed significantly in the survival (P < 0.0001), but not the death group (P = 0.7927). Conclusion: PMX-DHP, in addition to steroids and immunomodulators, may improve oxygenation and alleviate tachypnea by modulating the lymphocyte numbers and levels of various mediator against severe COVID-19 pneumonia. It may be better to perform PMX-DHP before multi organ dysfunction and lung injury has progressed. Furthermore, the early increase in lymphocyte counts after PMX-DHP might be an indicate a positive outcome.

ABSTRACT

This report describes the successful management of neurosurgical procedures with continuous infusion of recombinant factor IX (rFIX). A 1-year-old boy with severe hemophilia B was administered prophylactic therapy with rFIX after intracranial bleeding. We found the enlargement of an arachnoid cyst in a follow-up CT scan. He underwent marsupialization of the cyst under the continuous infusion of rFIX. FIX levels were examined in our hospital and the rFIX infusion rate was adjusted in an attempt to keep FIX levels above 90% intraoperatively, and 70% until his 7th post-operative day. We studied the pharmacokinetic profile of rFIX and found a half-time of 25 hours and mean in vivo recovery of 0.69 IU/dl/IU/kg. Reconstituted rFIX also retained at least 95% activity after 72 hours at room temperature. This is the first report of the perioperative management of a child undergoing a neurosurgical procedure under the continuous infusion of rFIX in Japan. Further studies are required before the routine use of this product for continuous infusion.
